Twitter stock plunges 20% in wake of 1m user decline

Social media company says fall is linked to action to delete fake accounts and admits it may well continue

Twitter's stock plunged 20.5% by the time the markets closed Friday - the second-biggest loss for Twitter's stock since the company went public in 2013.

Almost $5bn (3.8bn) has been wiped off the market value of Twitter after the social media service reported a drop of 1 million users following its action to delete fake and offensive accounts.
